Expandable styrene polymers

The invention relates to expandable styrene polymers for elastic polystyrene foams, comprising a) from 50 to 90% by weight of polystyrene and/or a styrene copolymer containing at least 50% by weight of copolymerized styrene, b) from 5 to 30% by weight of at least one styrene-soluble elastomer, c) from 5 to 20% by weight of at least one block copolymer containing styrene as one component, d) from 1 to 15% by weight, based on the sum of a), b) and c), of a low-boiling blowing agent, and, if desired, e) conventional additives in effective amounts,

A thermoplastic molding material contains, based on the sum of A and B,

Thermoplastic molding materials of improved green strength and impact toughness at low temperatures which are useful for producing injection moldings and are based on a TPU copolymer mixture, contain, based on 100 parts by weight,

Thermoplastic moldings materials of improved green strength and

Molding materials comprising a matrix of high impact polystyrene and rubber incorporated in the form of discrete particles contain not less than 50% by weight of polystyrene A and an effective amount of up to 50% by weight of a graft rubber B. The graft rubber B consists of from 40 to 95% by weight of an elastomeric core b.sub.1 and from 5 to 60% by weight of a shell b.sub.2, i.e. from 5 to 50% by weight of a first shell B.sub.21 of styrene and from 50 to 95% by weight of a second shell b.sub.22 of from 60 to 90% by weight of styrene and from 10 to 40% by weight of acrylonitrile, A and B, b.sub.1 and b.sub.2, b.sub.21 and b.sub.22 and styrene and acrylonitrile each summing to 100% by weight.
